摘　　要：为研究某隧道围岩突涌水问题,通过对比分析现场施工记录和相关监测数据,初步得到涌水成因并提出处治措施;此外,通过建立数值模型进行对比分析,并结合现场实测数据验证了处治措施的有效性。相关结果表明,软弱围岩体、地下水和降雨是发生隧道涌水的重要原因;采用隧道超前钻孔排水和围岩周边注浆的相结合的“先排后堵”措施可以有效控制围岩变形和涌水量。To study the problem of sudden water inrush from the surrounding rock of a section of a certain tunnel,by comparing the on-site construction records and relevant monitoring data,the causes of water inrush were preliminarily identified and treatment measures were proposed.In addition,numerical calculations were established to compare the operating conditions,and by integrating the on-site measured data the effectiveness of the treatment measures was verified.The relevant results indicated that weak surrounding rock mass,groundwater,and rainfall were significant causes of tunnel water inrush.The combination of tunnel advance drilling drainage and grouting around the surrounding rock can effectively control the deformation and water inrush volume of the surrounding rock.
